Here is a list of my suggestions:- Dark Souls I & II (Soon there will be a third)- Portal 1 & 2 (Great for the mind)- Batman: Arkham Games (Fun, simple combat with some puzzle solving)- Alien: Isolation (If you're looking to have a good old session of scares and crapping your pants)- Battlefield (Any game in the series, most preferably though the older ones. And yes they're still active as far as multiplayer goes)- Mafia 1 & 2 (Great story with great gameplay)
